Science activities you can do at the kitchen table
Science at its best is a prediction followed by a surprise. The science quests are built around that loop: predict whether five objects will float or sink, then test them in the sink; build the tallest paper tower you can in ten minutes, then measure it. The prediction is the important bit — it turns watching into thinking.
Other quests ask kids to explain something in their own words, like why the sky is blue, or to work out a big number, like how long light takes to travel from the Sun to Earth. Explaining something simply is one of the best tests of whether you understand it, and kids often find out they know more than they thought.

How to run physics & science quests at home
You don't need the app to use these. A few habits make them work much better.
- Ask for the prediction out loud, before the experiment starts, and write it down. No prediction, no experiment.
- Use what's in the kitchen. Fruit, coins, corks, a sponge and a spoon make a perfectly good float-or-sink lab.
- Let the paper tower fail. Wobbly towers are where kids discover triangles, folds and wide bases on their own.
- Answer “why?” with “what do you think?” first. Then look it up together.
How Tandomo uses these
The quests above are templates, not a fixed list. Each morning the app writes a new set for each child, adapting ideas like these to their age, their interests and anything you've asked it to focus on — so a pizza-sharing problem might become a pizza-sharing problem about their soccer team. Physics & Science usually appears as one or two quests in a mixed set of 7–10, alongside other subjects and plenty of off-screen time. Your feedback on the parent dashboard steers what comes next (more in the FAQ).
Physics & Science activities: common questions
Are the experiments safe to do at home?
They use everyday, low-risk materials like paper, water and kitchen objects. As with anything in the kitchen, younger children should have an adult nearby.
Do we need a science kit?
No. Every experiment in the starter library uses things most homes already have.
How does this fit with school science?
If you add the current school topic in the parent dashboard, explain-it and quiz quests will draw on it. The hands-on experiments stay general so they work for any curriculum.
